Abstract

L'invention concerne un connecteur d'alimentation électrique externe consistant en un connecteur (1) d'alimentation électrique externe venant se fixer à une unité de connexion côté véhicule (3) d'un véhicule, lequel comprend l'unité de connexion côté véhicule (3) et une unité de commande (300) afin de commander le fonctionnement de l'alimentation électrique vers l'unité de connexion côté véhicule (3) afin d'envoyer de l'électricité du véhicule vers l'extérieur, et comprend : un corps de dispositif (11) comprenant une unité de connexion externe (41) à laquelle une fiche électrique (53) d'alimentation électrique vers un dispositif externe est connectée ; un élément de régulation (12) pouvant commuter entre un état restrictif où la fiche électrique (53) ne peut pas être fixée à ou détachée de l'unité de connexion externe, et un état permissif où la fiche électrique (53) peut être fixée à ou détachée l'unité de connexion externe (41) ; une unité de sortie de signaux (18) afin d'émettre un signal vers l'unité de commande (300) ; et une section de détection (SW1). La section de détection (SW1) détecte si l'élément de régulation (12) est à l'état restrictif ou permissif, et lorsque l'état permissif est détecté, l'unité de sortie de signaux (18) émet un signal vers l'unité de commande (300) afin d'interdire l'alimentation en électricité vers le connecteur (10) pour fournir de l'électricité extérieurement.
